The Solitude of Prime Numbers

Alice (Alba Rohrwacher) and Mattia (Luca Marinelli) each want to be left alone with what happened to them as children. For Alice it was a skiing accident that left her with a damaged leg, and for Mattia it was the loss of his twin sister. Saverio Costanzo follows them from childhood into adulthood, two people who stay close enough to touch and never quite do.
